We present calculations of the chemical freeze-out temperature (T_ch) based on particle yields from STAR and ALICE measured at collision energies ranging from sqrt{s_{NN}} = 11.5 GeV to 5.02 TeV. Employing the Grand Canonical Ensemble approach using the Thermal-FIST Hadron Resonance Gas model package, we show evidence for a flavor-dependent chemical freeze-out in the crossover region of the QCD phase diagram. At a vanishing baryochemical potential, we calculate light and strange flavor freeze-out temperatures T_L = 150.2 +- 2.6 MeV and T_S = 165.1 +- 2.7 MeV, respectively.

从 RHIC-BES 到 LHC 能量的相对论重离子碰撞中化学冻结温度的风味和能量依赖性

我们根据 STAR 和 ALICE 的粒子产率计算化学冻结温度 (T_ch)，碰撞能量范围为 sqrt{s_{NN}} = 11.5 GeV 到 5.02 TeV。通过使用 Thermal-FIST 强子共振气体模型包的 Grand Canonical Ensemble 方法，我们展示了 QCD 相图交叉区域中与风味相关的化学冻结的证据。在消失的重化学势下，我们分别计算出淡味和异味的冻结温度 T_L = 150.2 +- 2.6 MeV 和 T_S = 165.1 +- 2.7 MeV。
